Hello. You don't say where it is that you live. Here in Arizona if you get stung by a scorpion you will get a numbness around the sting that will last for at least a week, maybe more.
Did you injure your pinkie? Did you hurt your neck? Your shoulder? Your elbow? Numbness in your little finger can come from just about anywhere.
Your ulner nerve was damaged. Does the ring finger and tip of middle finger hurt too? Did you injure it? I hurt mine lifting something too heavy. Try to sleep with your arm straight. Don't lean on you arm in bent position. Anti inflamitory med can help. It will go away.
